SeeDance 2.0 Fast (BudgetPixel)

SeeDance 2.0 Fast is what it says on the tin: the same four-mode SeeDance 2.0 (text-to-video, image-to-video with start/end frames, reference-to-video, video-to-video editing) at lower cost and latency - 160 credits per second against the standard 220. The trade is that it tops out at 720p; there's no 1080p or 4K in the resolution dropdown. For drafts, iterating on prompts, or any output that's going to be compressed down for social anyway, that's a fine bargain.

What's different from SeeDance 2.0

Nothing structurally - same mode logic, same mutually-exclusive input rules, same video edit socket with the same input-duration-at-half-rate billing on top of the output. The only real differences are price, latency, and the resolution ceiling. If you've already read the SeeDance 2.0 article, you know this node. The decision between the two is purely economic: 2.0 Fast for anything that doesn't need to come out at 1080p, 2.0 for the high-res hero clips.

The inputs that matter

• prompt - required; the edit instruction when video is connected.
• image / end_image - start and optional end frame for image-to-video.
• reference_images - up to 9 for reference-to-video; can't combine with image/end_image.
• video - the clip (2–15s, ≤100MB) for video-edit mode.
• length_seconds - 4–15.
• resolution - 480p or 720p. That's the whole list.
• generate_audio - off by default.

Output is video (VIDEO), core type - needs 2025+ ComfyUI.

How it works

The pack's standard hosted flow: media serialized and uploaded, a job created, polled until done, MP4 downloaded into the temp folder and wrapped as a VIDEO value. Video jobs take minutes; the "fast" is relative to the standard model's latency, not a local render. Interrupting the graph stops the wait but the job keeps running and billing server-side.

Install and key setup

ComfyUI Manager → BudgetPixel, or:

cd ComfyUI/custom_nodes
git clone https://github.com/budgetpixel-ai/comfyui-budgetpixel.git
pip install -r comfyui-budgetpixel/requirements.txt

Only requests. API key from a paid plan via BUDGETPIXEL_API_KEY or budgetpixel.json; never in workflow JSON.

Where people get burned

People pick Fast and then wonder why there's no 1080p option - read the resolution list before you commit, because the standard 2.0 node is the only route to high-res Seedance. The video-edit double-billing still applies (input duration at half rate plus output), so cost-estimate before an edit job. And the pack rules hold: force_rerun to defeat caching, paid plan required for the API.
